Einleitung Eine eher unbekannte Art des Mentalen Trainings ist das Training im Klartraum (Erla-cher, Stumbrys & Schredl, 2011-12). Im Klartraum ist sich der Träumende bewusst, dass er träumt, und kann dadurch den fortlaufenden Trauminhalt kontrollieren. Frühere Stu-dien zeigten, dass es möglich ist, motorische Aufgaben im Klartraum zu üben, um dadurch eine verbesserte Leistung im Wachzustand zu erreichen (Erlacher & Schredl, 2010). Jedoch ist wenig über die Prävalenz von Klarträumern im Sport bekannt. Methode Die Stichprobe umfasste 840 deutsche (D: 483 m, 357 w) und 1323 japanische (J: 1000 m, 323 w) Athleten. Das Durchschnittsalter betrug 20,4 Jahre (D: 21,6 J: 19,7). Die Teil-nehmer wurden in verschiedenen Sportarten – von Mannschaftssportarten (z.B. Basket-ball) bis Einzelsportarten (z.B. Leichtathletik) – rekrutiert und füllten einen Fragebogen zum Thema Sport, Schlaf und Traum aus. Die Athleten waren durchschnittlich 9,1 Jahre (D: 11.1, J: 7,9) aktiv und trainierten etwa 14,4 Stunden (D: 11.1, J: 16,7) pro Woche. Der Fragebogen erfasste auf einer 8-stufigen Skala die Klartraumhäufigkeit (Plus Definition: Für ein klares Verständnis von Klarträumen); die Anwendung (z.B. Training) für den Sport und, wenn dies bestätigt wurde, ob sportliche Verbesserungen erlebten wurden. Ergebnisse 47% (D: 57%, J: 41%) der Athleten gaben an, mindesten einen Klartraum erlebt zu ha-ben, 20% (D: 24% J: 18%) sind häufige Klarträumer (mit einem oder mehrere Klarträume pro Monat) und 9% (D 9% , J: 9%) nutzen Klarträume für ihren Sport, davon berichtet die Mehrheit, dass das Klartraumtraining die sportliche Leistung im Wachzustand verbessert. Diskussion Etwa die Hälfte der Athleten kennt das Klarträumen aus eigener Erfahrung, ein Fünftel sind häufige Klarträumer und etwa jeder zehnte Athlet nutzt Klarträume für seinen Sport. Für die deutsche Stichprobe ist die Prävalenzrate der Athleten ähnlich wie in der Bevöl-kerung. Für die japanische Stichprobe liegen keine repräsentativen Bevölkerungsdaten vor, auf der Grundlage der hier vorgestellten Fragebogendaten scheint es jedoch, dass kulturellen Unterschiede eine untergeordnete Rolle spielen.

BACKGROUND: Based on a subgroup analysis of 18-month BAsel Stent Kosten Effektivitäts Trial (BASKET) outcome data, we hypothesized that very late (> 12 months) stent thrombosis occurs predominantly after drug-eluting stent implantation in large native coronary vessel stenting. METHODS: To prove or refute this hypothesis, we set up an 11-center 4-country prospective trial of 2260 consecutive patients treated with > or = 3.0-mm stents only, randomized to receive Cypher (Johnson ; Johnson, Miami Lakes, FL), Vision (Abbott Vascular, Abbott Laboratories, IL), or Xience stents (Abbott Vascular). Only patients with left main or bypass graft disease, in-stent restenosis or stent thrombosis, in need of nonheart surgery, at increased bleeding risk, without compliance/consent are excluded. All patients are treated with dual antiplatelet therapy for 12 months. The primary end point will be cardiac death/nonfatal myocardial infarction after 24 months with further follow-up up to 5 years. RESULTS: By June 12, 229 patients (10% of the planned total) were included with a baseline risk similar to that of the same subgroup of BASKET (n = 588). CONCLUSIONS: This study will answer several important questions of contemporary stent use in patients with large native vessel stenting. The 2-year death/myocardial infarction-as well as target vessel revascularization-and bleeding rates in these patients with a first- versus second-generation drug-eluting stent should demonstrate the benefit or harm of these stents compared to cobalt-chromium bare-metal stents in this relevant, low-risk group of everyday patients. In addition, a comparison with similar BASKET patients will allow to estimate the impact of 12- versus 6-month dual antiplatelet therapy on these outcomes.

Objective: Identification of the ventrointermediate thalamic nucleus (Vim) in modern 3T high-field MRI for image-based targeting in deep brain stimulation (DBS) is still challenging. To evaluate the usefulness and reliability of analyzing the connectivity with the cerebellum using Q-ball-calculation we performed a retrospective analysis. Method: 5 patients who underwent bilateral implantation of electrodes in the Vim for treatment of Essential Tremor between 2011 and 2012 received additional preoperative Q-ball imaging. Targeting was performed according to atlas coordinates and standard MRI. Additionally we performed a retrospective identification of the Vim by analyzing the connectivity of the thalamus with the dentate nucleus. The exact position of the active stimulation contact in the postoperative CT was correlated with the Vim as it was identified by Q-ball calculation. Results: Localization of the Vim by analysis of the connectivity between thalamus and cerebellum was successful in all 5 patients on both sides. The average position of the active contacts was 14.6 mm (SD 1.24) lateral, 5.37 mm (SD 0.094 posterior and 2.21 mm (SD 0.69) cranial of MC. The cranial portion of the dentato-rubro-thalamic tract was localized an average of 3.38 mm (SD 1.57) lateral and 1.5 mm (SD 1.22) posterior of the active contact. Conclusions: Connectivity analysis by Q-ball calculation provided direct visualization of the Vim in all cases. Our preliminary results suggest, that the target determined by connectivity analysis is valid and could possibly be used in addition to or even instead of atlas based targeting. Larger prospective calculations are needed to determine the robustness of this method in providing refined information useful for neurosurgical treatment of tremor.

In 2010 the Nearctic leafhopper Penestragania apicalis (Osb.& Ball) was found for the first time in Europe. Altogether there are now 16 known localities in France, Switzerland, Germany and Austria indicating that the species is well established for a rather long period and more widespread in Europe and perhaps worldwide. As in North America it lives on honeylocust (Gleditsia triacanthos L.), overwinters in the egg stage and probably has one or two generations a year, with adults at least from late June until early October. It is yet unclear if it causes relevant damage to the host plant in Europe.
